It's apparently a slang name in some parts of US for the anode of a H/W heater. This is a long rod that fits into the top of a heater to attract metallic impurities in the water.
To replace the oil dip tube on a 1995 Ford Mustang, first, ensure the engine is cool and disconnect the negative battery terminal for safety. Remove any necessary components obstructing access to the dip tube, typically the oil pan. Once exposed, detach the old dip tube by pulling it out from its mounting location, then insert the new dip tube securely into place. Finally, reassemble any removed parts and reconnect the battery.
most dip tubes when they go bad don't look like anything at all because there's nothing left to it. when you pull out your cold side nipple which is 3 to 4" inches long then you can pull out your dip tube and inspect it. If your dip tube has cracks in it or holes then I would replace it . Most dip tubes in a water heater tank should be long enough so that the bottom of the dip tube is within 4 to 6" of the bottom of the tank.

The dip in water in a test tube is known as the meniscus. It is caused by the surface tension of the water, which causes it to curve slightly at the edges of the container. When measuring liquids in a test tube, readings are typically taken at the bottom of the meniscus.
